Object To investigate the chemical constituents from the stem of Pueraria peduncularis (Grah. ex Benth.) Benth. Methods The constituents were isolated on silica gel column chromatography. Their structures were elucidated by chemical and spectroscopic evidence. Results Ten compounds were comfirmed as 3-O-D-glucopyranosyl-(1→3)-β-D-6-O-methyl-glucuronopyranosyl]-3β, 15α, 23-trihydroxy-olean-12-en-16-one (Ⅰ), daidzein (Ⅱ), genistein (Ⅲ), daidzin (Ⅳ), genistin (Ⅴ), 3β, 15α-dihydroxy-olean-12-en-16-one (Ⅵ), lupeol (Ⅶ), betulinic acid (Ⅷ), α-spinasterol-glucopyranoside (Ⅸ) and α-spinasterol (Ⅹ). -3β, 15α, 23-trihydroxy-olean-12-en-16-one (Ⅰ), daidzein (Ⅱ), genistein (Ⅲ), daidzin (Ⅳ), genistin (Ⅴ), 3β, 15α-dihydroxy-olean-12-en-16-one (Ⅵ), lupeol (Ⅶ), betulinic acid (Ⅷ), α-spinasterol-glucopyranoside (Ⅸ) and α-spinasterol (Ⅹ). Conclusion Compound Ⅰ exhibited antimicrobial activity against Aspergillus niger. Compounds Ⅱ-Ⅹ were first isolated from this plant.
